Thanks! Still some errors that will pop up I already know of. I'm not clearing everything that needs to be so I'll get some artifacts I'm sure. Sucks the tank is still cycling and I can't play fully with the lights and cloud settings for a bit. Darn bacteria refusing to breed!

As you can see, I have completed the Event Previewer area, and have it accurately (or so it seems) predicting the next lighting effect be it sunrise, sunset, dawn, dusk, cloud, or sunlight. It also should be saying the correct ETA as well. The bottom diag numbers are time of dawn tomorrow.

Here is the code I used to get it. I also have heavily modified cloud code. I've added in a min/max cloud fade chance. It also no longer used the ReversePWMSlope. Any feedback would be welcome!

Thanks! The code for it should be in the other how do I area if you wanted just that how to bit.

I've edited a bit more and fixed some issues with the clouds not processing correctly. Also added in the ATO bit. I have a bucket on the side of my stand with RODI water in it and a pump. The pump has a float switch on it so I know if I'm about to suck air or not (LowATO). There is also an emergency float in the sump to act as a redundant check to the water sensor kit (HighATO). Other than that cleaned it up a bit and added better comments here and there.
